5 J. CAMPBELL CREPING' MACHINE Filed Dec. 20, 1924 6 Sheets-Sheet 6 ATTORNE Y5 Patented June 17, 1930 UNITED STATES SAMUEL J. CAMPBELL, OFGREEN BAY, WISCONSIN CREPING MACHINE This invention relates toimprovements in methods of, and machines for, creping pliable materials.r

A primary object of this invention is to provide an improved method ofcreping paper and other pliable materials in either a dry or a moistcondition and of producing in one operation stripes in the producthaving differing characteristics due to a difference in themode ofhandling the material along zones or longitudinal sub-divisions of thestrip of paper which is being creped. The improved method and theapparatus employed is particularly adapted for the crepmg of paper butit may also be employed for creping other substances, such as cloth ormetallic foil. j

Heretofore, flexible material, such as cloth, paper, and the like, hasbeen fed between intermeshing gears or equivalent devices for pressingor folding it in opposite directions to an extent determined by the sizeof the interact ing parts or teeth, The product of such machinesissometimes referred to as creped, but in modern practice the so-calledcreped paper has been more commonly produced by feeding moist paper overa roller to which it adheres and then stripping it from the roller bymeans of a so-called doctor plate, the edge or edges of which are soformed that when the paper is carried against it by the roller it iscrinkled and offset in a series of narrow ridges or folds more or lessirregular in form and produces the product commercially known as crepedpaper. The, friction of the moist paper upon the doctor plate, andparticularly upon doctor plates having uneven or corrugated surfaces, isthe principle agent in the development of the crinkles or folds in thepaper and therefore the operation becomes a delicate one, not only inthe degree of moisture, but in the form and position of the plate, toavoid tearing the paper and to produce the'precise effect desired forthe finished product. Considerable waste frequently results due totearing and improper crinkllng and with many materials, such as metallicfoil impervious to moisture and not sufliciently adhesive to a roller,it is impos Application filed December 20, 1924.

'sible to obtain the desired creping efiects by such methods.

The present invention is based upon the discovery of a new methodwhereby the above difficulties and disadvantages maynot only be overcomebut in the practice of which simple apparatus may be employed whichoperates upon a new principle and is capable of creping any material,whether wet or dry, and o producing a superior product or a variety ofproducts in which different zones or stripes may' be reduced withcorrugations or crinkles of difl'ering character and different designsmay be produced in color, character or contour.

13 am. aware that creped paper provided with designs in color has beenproduced by employing colored paper or paper having colored designsimprinted thereon preparatory to the creping operation; Attempts havealso been made to color creped paper or to imprint designs thereon incolor by operation of a press. Neither of these methods has proven verysatisfactory and it is a further object of my invention to provide meanswhereby a plurality of strips ofpaper of differing colors and marginalcontours may be superposed and interfolded during the creping operationin such a manner as to interlock the superposed sheets and impose uponone of the sheets serving as a backgroundanother sheet having'thedesired color designs and contours, the product having the appearance ofa single sheet of paper with designs in difi'ering colors. 7

Further objects of this invention are to provide means for utilizingyielding frictional surfaces in a narrow passage to facilitate thecreping operation; to provide means whereby the creping elements mayautomatically'assume an initial position for starting the crepingoperation and then yieldingly assume another position in which thecreping operation may be continuously carried on; to provide im rovedmeans for .feeding material into suc passages; to provide mecha nismcapable of being nicely ad'u'sted to produce precise effects in the'finis ed product; to provide means for subjecting the material duringthe creping operation to frictional portion thereof being cut away invertical section to expose mechanism which would otherwise be concealed.

Like parts are identified bythe same reference characters throughout theseveral views;

The improved method may be described as follows:

A strip of pliable material is pushed through a narrow passage betweentwo opposing walls which are sufliciently separated to allow thematerialto fold upon itself in projections of more or less irregular ingoperation to continue.

a series of crinkles, folds or zig-zag angular orm, said walls being insuch proximity to each other and capable of suflicient frictionaldetention of the material to cause the material to fold or deflectalternately in opposite directions from a point or line of frictionalcontact with the other. The strip is in the meantime continuously fedinto the space between said walls so as to cause a compressing orpacking operation whereby the material will be delivered from betweenthe walls in a crinkled or creped condition. By initially causing thewalls to converge toward the point of delivery the crinkling and packingoperation can be initiated, after which the walls may be allowed toassume a parallel position, the friction of the material upon the wallsbeing then suflicient to allow the pack- By varying the character orproximity of portions of the wall surfaces and by alternating movingsurfaceswith stationary surfaces along lines parallel to the plane inwhich the material travels, longiudinal strips may be produced in thefinished product due to the fact, that the material in one zone orstripe has been differently crinkled from that in another zone orstripe. Auxiliary to the method above described, superposed orcontiguous strips of paper of differing widths or marginal contours andof contrasting colors may be fed between the walls in such a manner asto not only simultaneously crinkle the strips but to interfold them ininterlocking relation, whereby the product may have the appearance of asingle strip of creped paper but with the contours, designs and colorsof one strip imposed upon theother strip along one face thereof, thewider strip serving as a background for the designs and 'colors of thenarrower strip.

I have discovered that when a strip of flexible material, (which may beslightly damp.- ened or prefectly dry), is forced edgewise into a narrowpassage, the walls of which are wholly or partially stationaryrelatively to the moving paper or material, the movement of the latterwill be retarded and the material deflected by frictional contact firstwith one of said walls and then with the other, such frictional contactbeing suflicient to cause the material travels sufiiciently to allow thefolds to accumulate and develop additional frictional resistance, thecrinkled or folded material may be packed within said passage andcompressed therein sufficiently to cause it to retain the creped orcrinkled condition after passing from between the platesi. e.'afterbeing delivered from the creping passage or receptacle.

I have also discovered that an increase in the frictional characteristicof the opposing wall surfaces compensates largely for an increase in thewidth of the creping receptacle. Smooth walls may be employed to roducethe usual degrees of crepe. By ad usting the walls so as toincreasetheir proximity, the undulations are shorter and sharper but lessprominent crinkles are produced than those found in the product wherethe walls are more widely separated. Also by causing certain portions ofthe walls to have a relative travel in the same direction that thematerial moves, lines of fold may be produced which curve and interlaceto a greater or less extent according to the Width of the travelingstrips or wall members and the relatively stationary portions.

Apparatus for carrying out my method may be constructed in a greatvariety of forms, some-of which are shown in the drawings and will nowbe described.

In the construction shown in Figures 1 to 4,

.' inclusive, the material A, which may be assumed to be a strip ofpaper, is drawn by a pair of feed rollers 16 and 17 from a supply roller18, the strip of paper passing from the supply roller over the idleguide rollers 19 and 20 and then downwardly in a substantially verticaldirection between the peripheral strip engaging surfaces of the feedrollers 16 and 17. The roller 18 has suitable end trunnions 24journalled in frame brackets 25. -The guide rollers 19 and 20 have theirsupporting shafts similarly journalled in frame brackets 26 and 27respectively. The axes of all of these rollers are of course parallel orsubstantially so.

The feed rollers 16 and 17 are respectively supported by shafts 34 and35 and the shaft 34 is journalled in eccentric bushings 36 which may berotatively adjusted in the frame bearings 37, the latter being dividedhori- 16 and 17 may be increased or diminished in accordance with therequirements, either at the time of the initial assembly of the ma-.chine parts or from time to tlme in accordance with the requirementsfor materials of differing thickness and pliability.'

Power is applied to the drive shaft 40 through a pulley 41 and istransmitted to the feed rollers-through the pinion 42 and a gear wheel43, fast on the shaft 34, which in turn transmitspower to the shaft 35through the intermeshing gear wheels 44 and 45 fixed to the respectiveshafts. These last mentioned gear wheels 44 and 45 are of the samediameter and therefore the shafts 34 and 35 will rotate at like speedsand the rollers 16 and 17 are adapted to act as feed rollers betweenwhich the web or strip of material may be engaged along a line of biteto draw the material from the roller 18 and impel it longitudinally intothe passage mentioned in the foregoing description of the improvedmethod and clearly indicated in Figure 3, corresponding passages beingalso illustrated in Figures 6, '9 and 12 as embodied in the modifiedforms of construction hereinafter to be described.

-' When referring to the line of bite between the feed rollers 16 and17, it is not intended to imply that this line of bite is necessarilycontinuous. Referring to Figure 2, it will be seen that each of theserollers 16 and 17 is provided with annular grooves 46 in its periphery,the grooves in one roller registering with those in the other and ineach roller the grooves are of substantially the same width or ofslightly greater width than the intermediate portions. The web or stripof paper A is gripped between these intermediate portions or annularribs 47, whereas the grooves are adapted to receive downwardly extendingconverging creping fingers 50 which in their lower end portions havecurved outer surfaces 51 concentric with the bases of the grooves inwhichthey are received and parallel vertically extending inner surfaces53 between which the web of material A is fed by the contacting portionsof the rollers-i. e.by the annular ribs 47. The vertically extendingsurfaces 53 constitute the opposing walls of the passage above referredto within which the creping operation is performed.

The creping fingers 50 have their upper 1 ends connected with mountings,each having the general form of a longitudinally extend the bracketcross bars 56. to which the channel bars are secured by bolts or screws60. Set screws 61 are employed to hold the channel bars rigidly againstthe front forks of their supporting brackets 56 and suitable shims .67may be introduced to facilitate an accurate positioning of the channelbar'59 and its associated creping fingers 50.

Each of the channel bars is provided with arms '62 connected therewithby bolts 62. These arms project outwardly and support weights 63, onefor each channel bar 59. The arms 62 pass through suitable aperturesnear the respective ends of the cylindrical weight 63, thereby providingfor an adjustment of the weight inwardly or outwardly upon itssupporting arms 62. Set screws 63 are employed to secure the weights tothe arms 62 when properly adjusted. The weights 63 tend to swing thechannel bar 59 and its supporting brackets 56 bodily about the sleeves55 upon which the brackets are respectively mounted and in a directionto swing the lower ends of the creping fingers toward those of the otherset associated with the opposing feed roller. The channel bars arepreferably provided with ribs 65 which enter suitable notches orrecesses 66 in the associated creping fingers 50, whereby the fingersmay be supported by these ribs and longitudinally adjusted along thechannel bar to which they are also secured by bolts 64.

The swinging movement of the creping finger mountings (brackets 56 andchannel bars 59) is regulated and limited as follows:

The bearing caps 37 at the respective sides of the machine are connectedby a spanner plate 68 which may conveniently be utilized to carrybrackets 27 forthe support of the idle guide roller 20. The, brackets 56have suitable projecting ears 73 and 73 extending inwardly from theinner and outer fork arms of the respective brackets. Stop screws 70extend through the ears 73 and have threaded bearings therein wherebythey may be adjusted in a position to engage the upper surface of thespanner plate 68 and limit the tilting movement of the associatedbracket in the direction of, the opposing bracket and feed roller.Similar stop screws 71 have threaded hearings in the ears 7 3' and arealso adapted to engage the upper surface of the associated spanner plate68 near its outer margin to limit the tilting movement of the associatedbrackets in the direction in which such brackets are urged by the weight63. The stop screws 70 and 71 are adjusted to allow a limited tiltingmovement of the brackets, the associated channel bars 59, and crepingfingers 50.

The weights 63 tend to hold the brackets in a position with set screws71 in engagement with the associated spanner plates 68, in whichpositions the surfaces 53 of the opposing creping walls convergedownwardly in a manner to initiate the crimping and packing operation.But during the creping operation the pressure of the creped paperagainst the opposing surfaces 53 of the respective sets of crepingfingers 50 will be suflicient to overcome the pull of the properlyadjusted counter-balancing wei hts 63 and separate the surfaces 53sufiicient y to allow the convolutions or folds of the creped paper tobe packed in the space or passage between the lower ends of the crepingfingers. In referring to the surfaces 53 as substantially parallel, itwill be understood that these surfaces are substantially parallel whensubjected to the pressure developed in the operation of packing thecreped paper between-them.

The weights 63 are so adjusted as to tend to maintain the lowerextremities of the creping finger sets in their initial position.- Insuch position the opposed sets of creping fingers form an initialresistance to the passage of the web, causing it at once to commence toundulate in the manner aforesaid. The weights maintain this resistanceconstant and at the same time permit the brackets 56 and the sets ofcreping fingers supported re spectively therefrom to oscillate to thefull extent which set screws 70 and 71 are adjusted to permit. As thepaper crepes and becomes compacted in the receptacle or passage formedby the opposing surfaces 53 of the creping fingers, such surfacesseparate to the extent permitted by the stop screw adjustment abovedescribed and become substantially parallel so that once the paper hascommenced to crepe, it will feed through the receptacle Without anyincrease of resistance during its passage. The surfaces 53 of crepingfingers 50 may be smoothly finished, such a finish being preferred wherefine creping is desired and where consequently it is necessary to locatesurfaces 53 of the two sets of creping fingers in close proximity.

The effect of the mechanism above described is very clearly indicated inFigure 14 which represents a web as it appears after passing through themachine. The portions 75 of the web which have been directly acted uponby the surfaces 53 of fingers 50 are crinkled or creped into coarseconvolutions, whereas the portion 76 of the web intermediate portions 75thereof have been acted upon only by the feed rollers and have not beendirectly subjected to the action of the creping fingers. Theseintermediate portions 76 will be more finely folded as indicated inFigures 14 and 16, and the broad convolutions at 75 will merge with thecreping which occurs at 76 to produce a novel and pleasing stripedeffect which has only heretofore been approached by paper which has beenwater marked elther before or after the creping operation.

Obviously the appearance of the product of the mechanism hereindisclosed may be varied within wide limits by varying the spacing offingers 50 to arrange them in pairs or in triplicate or in any otherpattern which may appeal to the trader Figure 7 illustrates a set offingers in which the individual fingers are so spaced as to associatethem in pairs and in series of threes. The sets associated with eachchannel bar may be so arranged throughout, or the arrangement may bevaried as desired tolany extent permitted by the roller channe s.

I have found that the character of the creplng produced by this machinemay be varied w thin Wide limits by varying the space between surfaces53 of the crepingfingers. Qbviously the distance between such surfacesmay be varied at will by adjusting set screws.70 and 71 on each of thebrackets carrying the sets of fingers, in which case any deviation fromthe normal approximate parallelism of surfaces 53 which may result fromaltering the bracket positions may be compensated for by introducing orremoving shims at 67. The shims may also be used to adjust the fingersindividually to roduce varying patterns of crepe as desire It hasalready been indicated above that when the surfaces 53 are closelyadjacent (as compared, of course, with the thickness of the web which isbeing fed therethrough) a fine creping will result. If the surfaces 53are more widel separated in proportion to the thickness of the web acomparatively coarse creping will result. If the fingers O are soadjusted that their surfaces comprising the receptacle through which theweb is forced are relatively very far apart, it may become desirable asindicated in Figure 6 to abrade the surfaces 53 of the opposed fingerswhich comprise the receptacle or passage. Thereby the retarding efiectof portions 53' of such fingers is increased as compared with theretarding effect which is possible where smooth surfaces are employed asat 53.

In Figures 8,9, 10 and 11 I have illustrated a preferred embodiment ofthe invention in which the general organization and principle ofoperation is the same as above described with reference to Figures 1 to4, inclusive, but

with structural features incorporated in the machine to facilitatevarious adjustments whereby the machine may be readily and accuratelyadjusted to suit the requirements of any given creping operation. In themachine illustrated in Figures 8 to 11, inclusive, the creping fingersare formed of resilient material whereby each individual finger isadapted to yield under the pressure of the the webs.

paper, although supported from a rigid mounting. This makes it possibleto employ a mounting in the form of an adjustable slide 90 movable alongthe upper surface of the frame and secured thereto by clamping bolts 91which pass through slots 92 in the slide to engage the frame and clampthe slide thereto. These slides 90 have at their respective endsupwardly extending webs 93 through which threaded adjusting rods 94 maypass, the rods 94 having threaded portions 95 at their inner ends whichare screwed into suitable sockets in the frame members 96 at therespective sides'of the machine. Collars 98 are secured on the rods 94upon opposite sides of the webs 93, whereby the adjusting rods areswiveled to squared, as indicated at 99, whereby a crank or wrench maybe applied to rotate the rods and thereby move the webs 93 and theassociated slides 90 inwardly or outwardly along the finger bars 50".

The outer ends of the rods are the frame to an extent permitted by theslots 92. Each of the slides 90 is provided at the inner end of itsassociated web 93 with a bracket plate 100 having projecting ears 101each provided with an arcuate slot 102: A

head may have a projecting arm 109 extending between the ears andactuated in opposite"- directions by screws 110 threaded in suitableapertures in the ears 108 and havingtheir inner ends bearing upon theopposite sides of the projections 109. By retracting one. of

the screws and advancing the other, the cross head 103 may be rotativelyadjusted and held in any desired position of adjustment by the screws110 and the clamping bolts 106.

On the inner face of each cross head 103 a vertically movable slide 115is mounted underneath a cross head shoulder 116. Adj usting screws 117pass through the cross head shoulder 116 and are threaded into suitablesockets in the slide 115, whereby said slide may be raised or lowered.To facilitate this adjustment from the sides of the machine, hand wheels118 are employed. These hand wheels are fixed to the shafts 119 upononeof which the idle guide roller 20 is loosely mounted. Motion maytherefore be transmitted from either hand wheel through its associatedshaft 119, beveled gear wheels 121 fixed thereon, and beveled gearwheels 122, each secured to one of the adjusting screws 117, therebraising or lowering the vertically movable slide 115.

The vertically movablev slide 115 supports U finger bars are bolted to aplate 130 which is The upper ends of the secured to the slide by screws131. The'lower portion of this plate is thickened at 132 and is providedwith channels to receive the finger bars. Clamping bolts 133 passthrough the plate between the finger bars and are provided with wedgeshaped heads 134 which engage in V-shaped recesses formed in thethickened portions of the plate and in the marginal portions of thefinger bars, as clearly shown-in Figure 12. The feed rollers 16 and 17',together with their mountings, are

the same as those disclosed in Figuresl to'4 and therefore the samereference characters are applied to these parts.

With the above described construction it is obvious that by looseningthe clamping bolts 12$ 91 andturning the adjusting screw rods 94,

the slides 90 may be caused to approach or recede from each other andthereby vary the dlsta-nce between the surfaces 53 of the sets ment issecured by turning the hand wheels 118 to raise or lower the verticalslides 115, thereby moving the creping passage or receptacle upwardly ordownwardly into greater or less proximity to the line of feed rollercontact with the materiali. e. to the socalled line of bite. The desiredrelative initial convergence between the surfaces .53 of the crepingfingers is obtained by rotatively adjusting the cross heads 103 upontheir supporting bracket plates 1.00. All of these adjustments arepossible from the sides of the machine and by means of the adjustingscrews it is obvious thatvery accurate results may be attained. Thefingers themselves are resiliently yieldable whereby their opposingsurfaces may assume substantial parallelism under pressure resultingfrom the, creping and packing operations.

Referring to Figure 13, it will be observed that a single feed roller 17is associated with a set of creping fingers 50 which may be supported inany convenient manner such, for example; as the means disclosed inFigure 3 or the means disclosed in Figure 9. But instead of employing acompanion feed roller, such as the roller 16 in Figures 3 and 9, acreping plate 140 may be employed. This plate may be continuous alongthe working area of the roller 17 and may be provided with a shoulder at141 substantially coinciding with the line of bite or pressure contactwith the material fed between it and the roller 17 Below this shoulder acreping wall 142 depends, the inner surface of this wall being spacedfrom the surfaces 53 of the creping fingers associated with the roller17, thereby forming av receptacle or passage within which the crepedmaterial may be packed or pressed. It is not material whether the wall142 is continuous or whether it comprises a series of fingers similar tothe lower ends of'the fingers 50. The contour of the inner face of thewall 142, whether continuous or interrupted, flat or ribbed, will ofcourse affect the appearance of the product but will not otherwiseaffect the mode of operation of the machine.

Where it is desired to impress upon a surface of the creped paper anysuitable design in contour or color, I employ an additional supplyroller as indicated at 144 in Figure 1. A strip A of colored orspecially contoured paper may be drawn from this roller over the idlerollers 19 and 20 and fed into the creping receptacle with the strip Awhereupon both strips will be creped simultaneously and interfolded inthe creping operation so intimately that both strips or sheets will beheld together as one strip or sheet of paper, although they can readilybe pulled apart if desired. In this manner results can be secured asindicated in Figures 14 and 15, wherein Figure 14 illustrates theproduct of the machine shown in Figure 1 (or 9) with a single strip ofpaper drawn from feed roller 18, whereas Figure 15 illustrates theproduct of the same machine or machines with an additional strip ofpaper of less width and of contrasting collar drawn from an auxiliaryfeed roller 144. s

, The crepe paper produced in the manner above described ishighlyelastic and may be considerably distended. without materiallyaffecting its appearance except as to a widening of the corrugations orcrinkles. The folds or reverse bends in the strip or sheet of crepedmaterial will ordinarily be sharp due to the pressure exerted upon thematerial in the passage during the packing operation.

It will of course be understood that the means for advancing the web orstrip of material and the walls of the creping receptacle or passagemust be located in close proximity whereby the material will bedelivered immediately and directly from the feeding means into thepassage in order that the folding material will necessarily be broughtinto contact with the passage. It is also necessary to the packingoperation that the feeding means be located at the top of the passage orreceptacle and in such proximity thereto that paper or other materialfed edgewise intothe passage may be packed therein with sufficientpressure to fix the convolutionsor folds in permanent form. After thecreping operation has been properly commenced, the folding will ofcourse take place immediately below the feeding line or line of bite.

It will also be understood that the depth of creping, viz :the thicknessof the creped material, will be determined by the distance between thesurfaces of the passage or receptacle, inasmuch as the material willcontact first with one wall and then with the opposing wall while it isbeing creped, and these contacts will be maintained. during the packingoperatiom It will further be understood that the creping fingers may benon-adjustably fixed in the indicated positions of parallelism. In sucha case, it will be necessary for the operator manually or otherwise toofi'eran initial resistance to the issue of the paper from thereceptacle. This may be done merely by obstructing the receptacle outletwith the hand and after the creping operation has commenced and packingof the paper has resulted the creping will continue indefinitely.
